A cache by a stream in the woods near exit 11 of the M8 motorway.
This is not a park & grab - it involves a challenging tree climb!! If you happen to have climbing equipment then have it in the car in case it is needed. (We didn't use any equipment).
GPS was bouncy under the tree so the coordinates may be a little off. They should bring you to a large mossy oak tree next to a bridge. The cache is up this tree. It should be visible from the ground. (There is a picture of the tree in the gallery).
A waypoint is available for easy parking. It should be possible to park closer to GZ.
The cache is a bison tube. BYOP.
